SSHTunnel with key value (not path)

Question

I have an SSH key stored in a variable as I'm using a cloud function and don't have access to a filesystem. For example:

with SSHTunnelForwarder(
   ssh_address_or_host='my-host', 
   ssh_username='my-user',
   ssh_pkey='/home/david/.ssh/id_rsa' # this
) as tunnel:

Instead of passing the path to the ssh_pkey file, how can I hardcode that as a string? Yes, I will move it to an environmental variable or something else, but for testing, is there a way to pass it a string?

Answer 1

As @TimRoberts commented, the ssh_pkey accepts paramiko.pkey.PKey instance, not only a path to a key file.

For an example how to construct PKey from a string, see:
